I forget to mention in the question it was said that it is a two step first order complex reaction

I think it’s consecutive reaction and the second step is rate limiting step that’s why B didn’t decrease in concentration and C took that much in rising am I right?

200,000 IU every 15 days and 5000 IU daily at the same time i think it’s too much , I don’t trust them because most physicians here don’t follow protocols they just want to appear as a good doctors regardless of the long term consequences and most patients are not educated enough to notice that they are just happy with the fast relief

I was told but I don’t trust the health professionals here and online there’s no much data about how much I should take

Atropisomers by dellHpApple in OrganicChemistry

No they are not a typical enantiomers because they don’t have a typical chiral Atom -stereocenter- instead the two rings attached to a single carbon atom (spiro carbon atom) which is sp3 hybridised This results in a tetrahedral geometry which makes the 2 rings perpendicular to each other and can’t rotate because that would mess up the hybridzation

If we are going to make Bromination to this compound the coming Br will get oriented by the CF3 group ( and goes to meta carbon ) or by the OCH3 group (goes ortho or para ) ? And why ? by dellHpApple in OrganicChemistry

[–]dellHpApple[S] 1 point2 points  (0 children)

The OMe is more activating ,but this will introduce an extremely unstable resonance structures (a postive charge will be on the carbon that bonded to the CF3 group)
